If you want to access the fields of a class or struct you can use .tupleof:

class Foo { int a; }
Foo.tupleof;

You can have a look how this is used in my serialization library Orange:

Interesting templates/functions would be:

* hasField
* fieldsOf
* TypeOfField
* nameOfFieldAt
* setValueOfField
* getValueOfField
